  Bluetooth is not a random device connected to the MMC/SD controller. It
is function 2 of the SDIO device.

Fix the address of the bluetooth node. Also fix the node name and drop
the label.

Dear Chen-Yu,


Thank you for your patch.

Excuse my ignorance: Is this a cosmetic fix or does it fix the device 
somehow?

To avoid confusion, would it be possible to use sdio as a “name”.

Names must be generic and descriptive; this is the Bluetooth part of the MT7921s
hence it's called "bluetooth". If its functionality was "sdio", it'd be as such,
but this is BT anyway.

"sdio@xxx" would be applicable to, for example, a controller that provides support
exclusively for SDIO (with no support for eMMC/SD).

Regards,
Angelo

It's a cosmetic change, since the driver already searches the whole device
tree for the specific compatible string. However it also fixes the device
tree description to match the actual hardware.

Not sure where the confusion is. Bluetooth is the functionality this
SDIO function provides.
